Description
CROSS REFERENCE TO RELATED APPLICATION
The priority application Japan Patent Application No. 2008-097416
upon which this patent application is based is hereby incorporated
by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a rescue terminal structure for
use in supplying electrical power to a vehicle by connecting a
booster cable to a rescue terminal of for example an electrical
junction box when a battery of the vehicle is dead.
2. Description of the Related Art
FIG. 6 shows a conventional rescue terminal structure (for example,
see FIGS. 1 to 4 of Japanese Patent Application Laid-Open
Publication No. 2004-134215).
The conventional rescue structure has a bus bar 52 provided on the
plate-shaped block body 51 made of insulating synthetic resin and a
rescue terminal 53 upstanding from the bus bar 52. A bolt 55 on the
side of the block body 51 is passed through a hole 54 of the bus
bar 52. An electrical wire (not shown) connected to a positive
terminal of a battery is fastened by a nut and connected to the
bolt 55. When the vehicle's battery is dead, the booster cable 6
(see FIG. 7) for electric power supply is connected to the rescue
terminal 53.
Japanese Patent Application Laid-Open Publication No. 2004-134278
discloses a conventional rescue terminal structure wherein a cover
(not shown) made of insulating synthetic resin is mounted to a
block body (51), the cover has an opening through which the rescue
terminal (53) protrude to an outside, and the opening is covered by
a small inner cover (not shown). The block body (51) and the cover
constitute a junction box body, and the junction box body, the bus
bar (52), the rescue terminal (53), and a bolt (55) constitute the
electrical junction box (see FIG. 1).
As shown in FIG. 6, the rescue terminal 53 has for example, a
U-shaped cross-section. Also, it may be in a shape of a rectangular
column. The electrical junction box is installed, for example, in a
hood of a hybrid vehicle and the battery (not shown) is installed
in a rear trunk. Since the battery is covered by a cover, it is not
possible to connect a booster cable 6 to the battery as such when
the battery is dead. A driver therefore has to open the hood and
connect an end of the booster cable 6 to a positive rescue terminal
53 of the electrical junction box. The other end of the booster
cable 6 is connected to a positive electrode (not shown) of a
rescue vehicle's battery that supplies electric power to the dead
battery of the driver's own vehicle.
As shown in FIG. 7, the booster cable 6 includes a clamping portion
(crocodile clip) 7 that is made of electrically conductive metal
and is closed by a force of a spring). The clamping portion 7 is
connected to an end of an electrical wire 9. The clamping portion 7
includes a pair of chuck pieces 8 that each have an edge-shaped end
8a that holds the rescue terminal 53 and right and left
sawtooth-like teeth 8b. The pair of chuck pieces 8 are energized in
a closing direction by a force of a torsion coil spring (not shown)
with the hinge 8c acting as a point of support.
SUMMARY OF THE INVENTION
A drawback of the conventional rescue terminal structure identified
by the inventors of the present invention is as follows. When the
battery is dead, the driver might be in a hurry to connect the
booster cable to the rescue terminal. Also, it can happen that the
booster cable might be pulled. In such cases, the clamping portion
might be inadvertently detached from the rescue terminal, failing
to stably and safely supply electric power to the battery waiting
for revival.
In view of the above-identified problem, an object of the present
invention is to provide a rescue terminal structure that allows the
clamping portion of the booster cable to be firmly connected to the
rescue terminal of the bus bar.
In order to achieve the above objective, the rescue terminal
structure according to one embodiment of the present invention
includes a terminal supporting plate formed in one piece with a
body of a fuse block, the supporting plate and the body being made
of insulating synthetic resin, a plurality of elongated ribs
protruding on one surface of the terminal supporting plate; and a
rescue terminal of a bus bar mounted in the body of the fuse block,
the rescue terminal being arranged along the other surface of the
terminal supporting plate such that both the rescue terminal and
the rib are clamped at one time by a clamping portion of a booster
cable.
With the construction and arrangement described above, the ribs are
provided on one surface of the supporting plate, and the rescue
terminal is positioned on the other (opposite) surface of the
terminal supporting plate. Accordingly, the clamping portion of the
booster cable for emergency power supply clamps both the rescue
terminal and the ribs at one time, and the edge-shaped end and the
sawtooth-like teeth of the clamping portion bite into the elongated
rib or ribs so that the clamping portion is firmly secured with a
large frictional force to the rescue terminal of the bus bar which
is connected to the battery. When the driver or an operator is in a
hurry to connect the clamping portion to the rescue terminal, or
when a pulling force acts upon the clamping portion after the
booster cable is connected, the clamping portion is prevented from
being displaced or detached from the rescue terminal and thus the
electric power can be safely and stably supplied.
Preferably, the plurality of ribs are parallel to each other. When
the clamping portion of the booster cable clamps the rib along a
length thereof, the plurality (if not all) of ribs are at one time
clamped by the clamping portion of the booster cable (more
specifically, by the edge-shaped ends of the clamping portion) and
the edge-shaped ends bite into the ribs. Even when the pulling
force acts upon the booster cable, the end of the clamping portion
is in contact with the rib with a frictional force larger than the
pulling force. Accordingly, undesirable displacement and detachment
are prevented and electrical power can be supplied more safely and
stably. The edge-shaped end of the clamping portion bites into the
rib when the clamping portion of the booster cable is attached to
the terminal supporting plate from above.
Preferably, a thickness of the rib is such that the rib is placed
under compressive deformation when the rescue terminal and the rib
are clamped by the clamping portion, so that the clamping portion
of the booster cable bites into the rib to generate large
frictional force and the displacement and detachment of the
clamping portion form the rescue terminal is effectively
prevented.
Preferably, the body of the fuse block has a hole for inserting the
rescue terminal therethrough and allowing the rescue terminal to be
provided along the other surface of the terminal supporting plate.
By virtue of the hole, the bus bar is accommodated in the block
body and at the same time the rescue terminal is allowed to be
exposed via the hole to an outside with the rescue terminal
slidably and smoothly placed on the other surface of the terminal
supporting plate. The hole is a slit slightly larger than a
cross-section of the plate-shaped rescue terminal. The hole defines
the position of and supports the rescue terminal. Thus, arrangement
of the rescue terminal is facilitated.
Preferably, the body of the fuse block is accommodated in a frame
made of insulating synthetic resin, the frame has an opening that
allows the rescue terminal and the terminal supporting plate having
the ribs to be exposed to an outside of the frame, and the frame
has an inner cover that covers the rescue terminal and the terminal
supporting plate having the ribs.
With the construction and arrangement described above, electrical
junction box, which is constituted for example by a body of the
fuse block, the bus bar, the frame, and the fuses mounted to the
body of the fuse block. It is preferable that a cover is mounted to
the frame and the inner cover resides inside of the cover. Also, it
is preferable that other blocks, units, and components other than
the body of the fuse block are accommodated together in the frame.
In a state where the terminal supporting plate and the rescue
terminal are in contact with each other in the thickness direction,
the rescue terminal is passed through and supported by the opening
of the frame so as to be exposed via the frame to an outside. The
inner cover of the frame serves to protect the rescue terminal and
isolate the rescue terminal from other components of the electrical
junction box. Connection of the booster cable to the rescue
terminal is done with the inner cover opened. By a region around
the opening of the frame, the rescue terminal is isolated from
electrical components such as a fuse and a connector on the side of
the block body, and the fuse and connector on the side of the block
body is protected against adverse effect that might be caused by
connecting the booster cable to the rescue terminal.

DESCRIPTION OF AN EXEMPLARY EMBODIMENT
A rescue terminal structure according to one embodiment of the
present invention is described below with reference to FIGS. 1 to
5.
Referring to FIG. 1, the rescue terminal structure includes three
constituent parts, i.e., a terminal supporting plate 2, a plurality
of ribs 3, and a rescue terminal 5.
The terminal supporting plate 2 is formed in one piece with a body
of a fuse block made of insulating synthetic resin (block body 1 or
junction box body). The terminal supporting plate 2 has the
plurality of elongated vertical ribs 3 extending parallel to each
other and each upstanding on the outer surface of the terminal
supporting plate 2.
The bus bar has the rescue terminal 5 in a shape of a flat vertical
plate. The bus bar 4 is made of electrically conductive metal (see
FIG. 2). The rescue terminal 5 is arranged along and in contact
with an inner surface of the terminal supporting plate 2 (i.e., a
surface opposite the above-mentioned outer surface on which the
ribs 3 are provided). A clamping portion 7 (a clip in a shape of a
crocodile or alligator's mouth) of a booster cable 6 (see FIG. 7)
bite to some extent into ribs 3 made of synthetic resin and thus
clamps the rescue terminal 5 and the ribs at one time so as to be
connected to the rescue terminal 5.
The ribs 3 according to the preferred embodiment are seven in
number and extend parallel to each other. The central rib 3' is
formed on and protrudes from a wall (indicated by a reference sign
11 for simplicity) of a hole 11, the wall bridging the two ribs 3.
The hole 11 has a U-shaped cross-section and is formed for example
by die cutting or injection molding. The hole 11 is provided at the
central portion widthwise of the terminal supporting plate 2 with a
small amount of protrusion relative to those of the other ribs 3.
This configuration of the central rib 3' and the hole 11 is
intended to form an injection-molded locking projection (not shown)
on the block body 1. The locking projection configured to be
brought into engagement with a locking hole 10 formed
(injection-molded, die-cut or punched, for example) on the rescue
terminal 5 (see FIG. 2). The ribs 3 other than the central rib 3'
are formed on and protrude from the outer surface of the terminal
supporting plate 2 with a large amount of protrusion L1 relative to
that of the central rib 3'. Note that the ribs with the reference
sign 3 may generically include the central rib with a reference
sign 3'.
A height (degree of protrusion) of the rib 3 is larger than a width
(or thickness) W of the rib 3 so that the rib 3 can be readily
compressed and deformed in a direction orthogonal to the outer
surface of the rescue terminal 5. The plurality of ribs 3
constitute a structurally weakened portion of the terminal
supporting plate 2. Also, the supporting plate 2 is reinforced by
the wall 11 with a U-shaped cross-section at the center of the
supporting plate 2. In a sense, by virtue of the wall 11 bridging
two ribs 3, the supporting plate 2 can be strengthened by the ribs
3 which constitute the structurally weakened portion. Accordingly,
the deformation and breakage of the supporting plate 2 as such is
prevented even when the clamping portion 7 (see FIG. 7) is abruptly
attached to or inadvertently detached from the supporting plate
2.
The ribs 3 and 3' may upstand to the same degree (with the same
height) from the terminal supporting plate 2 if the locking hole 10
(see FIG. 2) and the locking protrusion are provided at a portion
of the bus bar other than the rescue terminal 5. The width (or
thickness) of the rib 3 is so small that the rib 3 can be clamped
by the clamping portion 7 and subjected to compressive plastic
deformation (or elastic deformation). The width W, the height (or
degree of protrusion) L1, and an overall length L2 of the rib 3 may
vary insofar as the rib 3 clamped by the clamping portion 7 is
placed under the compressive plastic deformation (or elastic
deformation).
The clamping portion 7 (see FIG. 7) clamps the rescue terminal 5
and the rib 3 at one time between a first chuck piece and a second
chuck piece from above and substantially vertically. However, even
when the clamping portion 7 clamps the rescue terminal 5 and the
rib 3 more or less slantwise in the rescue terminal's width
direction, deviating from the above-described vertical clamping
direction, an end 8a (FIG. 7) and a saw-tooth-like teeth 8b of the
chuck piece bite into the ribs 3 so that the clamping portion 7 is
not detached accidentally or displaced inadvertently.
The terminal supporting plate 2 is formed at an end of the block
body 1. The terminal supporting plate 2 faces an inside of the
block body 1. The ribs 3 faces an outside of the block body 1. An
upper end 3a of the rib 3 and an upper end of the supporting plate
2 substantially coincide with each other, so that the upper end of
the supporting plate 2, and the rescue terminal 5, which is a
rectangular member over an entire width of the supporting plate 2,
upwardly projects until reaching an upper end of the supporting
plate 2.
A lower portion of the rib 3 terminates at a horizontal thick wall
12. The wall 12 is also formed in one piece with the lower end of
the supporting plate 2. Also, the length of the rib 3 is orthogonal
to the wall 12. Further, the thick wall 12 integrally continues to
a vertically extending outer wall 13 of the block body 1. The outer
wall 13 has a locking arm 15 that engages a frame 14 (see FIG. 5)
made of insulating synthetic resin and also has vertically
extending sliding rails 16. A plurality of fuse-mounting portions
17 and 18 are formed inside of the block body 1. The fuse-mounting
portions 17 and 18 are arranged in parallel with each other.
As shown in FIG. 2, the bus bar 4 is accommodated in the block body
1. The rescue terminal 5 extends in a shape of an L and integrally
continues to an end of the bus bar 4. A bus bar's terminal 19 for
use in connecting a fuse to the body 1 is placed under the
fuse-mounting portions 17, 18 of the block body 1 when the fuse
block and the bus bar 4 are assembled.
Referring to FIG. 3, the bus bar 4 is mounted in the block body 1
from underneath guided by a vertical groove (not shown). As shown
in FIGS. 3 and 4, the bus bar 4 according to the preferred
embodiment is made for example by die-cutting and shape-processing
an electrically conductive metal plate such that first and second
side plates 21 and 22 extend vertically at both sides of the
horizontal bottom plate 20. The clamp terminal 19 and a tab
terminal 23 for connecting a connector to the block body 1 are
formed in one piece with the first and second side plates 21 and
22, respectively (see FIG. 4). One end of the metal plate extends
vertically to constitute the rescue terminal 5 at a front end of
the side plate 21. Meanwhile, a plate 25 having a tab terminal 24
in one piece therewith is formed at a rear end of the second side
plate 22. The tab terminal 24 is for use in electric power
supply.
Still referring to FIG. 3, the second side plate 22 of the bus bar
4 is disposed under the fuse-mounting portion 17', which is a
second row (viewed from the proximal side of the block body 1), and
a connector housing 26. The first side plate 21 of the bus bar 4 is
disposed under the fuse-mounting portion 17 in a third row and a
connector housing (a fusible link mounting portion) 18'. The
clamping terminal 19 is accommodated in the fuse-mounting portion
17, and the tab terminals 23 are accommodated in the connector
housings 18' and 26. Another downstream-side bus bar (not shown) is
provided for the other fuse-connecting portions.
The rear-end tab terminal 24 is accommodated in the connector
housing 27 provided at the rear side of the block body 1. The tab
terminal 24 is connected to a connector (not shown) of a wiring
harness that is connected to a positive electrode of a vehicle's
battery (not shown). A terminal (not shown) of a wiring harness
connected for example to an alternator is secured by a bolt and
connected to the rear side plate 25 via a high current fuse (not
shown) provided in an opening 28.
The terminal supporting plate 2 is formed and upstands on an upper
wall 29 at the front side of the block body 1. A slit-shaped hole
30 for insertion of the rescue terminal 5 is provided on the upper
wall and extends in the vertical direction. A flat surface (for
simplicity represented by the sign 2) of the supporting plate 2 is
found above the hole 30. Also, the surface of the supporting plate
2 continues integrally to the inner wall of the hole 30.
With the bus bar 4 accommodated in the block body 1 from below, the
rescue terminal 5 is passed from below through the slit-shaped hole
30 and extends along and in contact with the inner surface of the
supporting plate 2. The upper openings of the fuse-mounting
portions 17 and 17' are arranged parallel to each other on the
upper wall 29 of the block body 1. It should be noted that the
adjectives such as front, rear, right, and left that appear in this
specification is intended for not specific technical implication
but convenience of explanation.
Referring now to FIG. 5, the block body 1 is accommodated, from
below, inside of the substantially rectangular frame 14. A fuse
block 1', which is an assembly including the block body 1, a bus
bar 4, and a fuse (not shown), is placed inside of the wall 31 of
the frame 14.
The frame 14 has in one piece therewith (a) an opening 32 that
makes the rescue terminal 5 and the terminal supporting plate 2
protrude upward, (b) a horizontal wall 33 defining the opening 32,
(c) a pair of vertical walls 34 upstanding such that the horizontal
wall 33 is positioned between the vertical walls 34. These are
provided at one end of the frame 14. Also, (d) a resilient
engagement piece 35 for engagement of an inner cover is integrally
formed on the upper portion of one of the vertical walls 34. A
hinge portion 36 for opening and closing of the inner cover is
integrally formed on the upper portion of the other vertical wall
34.
The rescue terminal 5 and the terminal supporting plate 2 upwardly
projecting out of the opening 32 are covered by the inner cover
(not shown) made of insulating synthetic resin for protection and
isolation. The horizontal wall 33 at a periphery of the opening 32
makes the rescue terminal 5 spaced away from the fuse-mounting
portions 17, 18 of the fuse block 1', thus improving isolation of
the rescue terminal with respect to the fuses and the connector
terminals (not shown).
Having described the basic configuration and arrangement of the
rescue terminal structure according to one embodiment of the
present invention, the following summarizes a mode of operation of
the same rescue terminal structure.
First, when the battery of the vehicle is dead, a driver or an
operator opens a cover (not shown) made of insulating synthetic
resin covering the upper opening 31a of the frame 14. Next, the
operator opens the inner cover (not shown). Further, he or she
connects the clamping portion 7 (the crocodile clip) of the booster
cable 6 (see FIG. 7) to the rescue terminal 5 and the supporting
plate 2 such that both the rescue terminal 5 and the ribs 3 of the
supporting plate 2 are clamped by the two chuck pieces of the
clamping portion 7.
At this point, the end 8a and the sawtooth 8b of the first chuck
piece 8 of the clamping portion 7 is spring-biased and brought into
contact with the rescue terminal 5. The end 8a and the sawtooth 8b
of the other chuck piece 8, energized by the biasing spring, bite
into the rib 3 of the supporting plate 2 so that the clamping
portion 7 and accordingly the booster cable 9 are firmly secured
and connected to the rescue terminal 5. Since the rib 3 is formed
thin and made of insulating synthetic resin, the rib 3 yields to
the spring force of the spring in the clamping direction of the
clamping portion 7 and placed under compressive deformation with
the end 8a and the sawtooth 8b biting into the rib 3.
Thus, even when the operator is in a terrible hurry to connect the
clamping portion 7 to the rescue terminal 5, or even when the
attached booster cable 6 is pulled, the clamping portion 7 is
effectively prevented from being detached from the rescue terminal
5 and electrical power can be stably and safely supplied to the
battery.
Although the preferred embodiment of the present invention has been
fully described, the appellation of the components constituting the
rescue terminal structure may be altered as appropriate for
convenience of explanation. For example, although the fuse block 1'
as such is defined as the electrical junction box in the preferred
embodiment, the assembly incorporating the fuse block 1', the frame
14, and the cover (not shown) may be referred to as the electrical
junction box.
In the preferred embodiment, the rescue terminal structure is
incorporated into the electrical junction box. However, when the
rescue terminal 5 is provided not on the electrical junction box
but on the block body 51 made of insulating synthetic resin (see
FIG. 6 illustrating the conventional device), the terminal
supporting plate 2 having the ribs 3 may be formed in one piece
with the block body 51 and the rescue terminal 5 may be arranged
along the terminal supporting plate 2.
In the preferred embodiment, in order to connect the booster cable
6 to the rescue terminal 5 from above and in a vertical direction,
the terminal supporting plate 2 upstands vertically and the ribs 3
are formed on the terminal supporting plate 2 orthogonal to the
outer surface of the terminal supporting plate 2. However, it is
also possible to form the ribs 3 on the terminal supporting plate 2
such that the ribs are arranged horizontal to each other when the
booster cable 6 is to be connected to a lateral side of the rescue
terminal 5. In this case, it is preferable that the block body 1
includes an isolating portion that supports the clamping portion 7
so that the clamping portion 7 is prevented from deviating downward
due to her own weight.
Although, in the preferred embodiment, the ribs 3 extend parallel
to each other, it is also possible to provide a lattice of ribs
extending vertically and ribs extending horizontally. In this case,
each rib 3 is to have a height and a width that allow the rib 3
clamped by the clamping portion 7 can be compressed and deformed.
An amount (or a depth) of compressive deformation has only to be
such that the rib traps the clamping portion 7, exerting large
frictional force that prevents displacement of the clamping portion
7.
In the preferred embodiment, the rescue terminal structure is
incorporated into the fuse block 1'. However, the rescue terminal
structure of the present invention is also applicable to devices
other than the fuse block 1' such as a relay block and a connector
block (not shown). In that case, the body 1 of the fuse block will
be read as a relay block body and a connector block body,
respectively.
Having now fully described the preferred embodiment of the present
invention, it is clear that the descriptions and explanation
contained herein are only cited by way of example rather than
limitation, and therefore the present invention can be effectuated
with modification and variation without departing from the scope
and sprit of the present invention.
